Offering for the Feast of Weeks

The first of the firstfruits of thy land thou shalt bring into the house of יהוה thy God. Thou shalt not seethe a kid in his mother’s milk. Exodus 23:19 (34:26)

As for the oblation of the firstfruits, ye shall offer them unto יהוה: but they shall not be burnt on the altar for a sweet savour. And if thou offer a meat offering of thy firstfruits unto יהוה, thou shalt offer for the meat offering of thy firstfruits green ears of corn dried by the fire, even corn beaten out of full ears. And thou shalt put oil upon it, and lay frankincense thereon: it is a meat offering. And the priest shall burn the memorial of it, part of the beaten corn thereof, and part of the oil thereof, with all the frankincense thereof: it is an offering made by fire unto יהוה. Leviticus 2:12,14-16
